TREATMENT or CONTAINERS.

Application tiled August 1, 1925. Serial No. 47,458.

My invention relates to improvementsin the treatment of containers, and more particularly has reference to, and is illustrated in the accompanying dra-Wings in its appli-` cation to, an apparatus in the form ot an attachment for greasing the insides of baking pans particularly adapted for use in combination With a pan Vfeeding conveyor such as used in combination i with baking ovens.

Referring to the accompanying drawings, Ihave illustrated in Fig. 1 in perspective, parts being broken away, a suitable formfof apparatus embodying an applicationof my invention. Fig. 2 is an enlarged detail of the brush or grease swabber device. y

3 indicates the drive shaft of the pan conveyor, such as commonly employed in conibination with baking ovensand is provided at one end Witha beveled pinion 11, which meshes with the beveled pinion 5 upon the counter-shaft 6, mounted in suitable brackets 7, and carrying cams 8, 9, and 10. Upon these cams ride the rollers 11, 142, 13, respectively, the latter two being secured to levers 12', 13 upon the shaft 14, mounted in the brackets 15, and the former mounted in they stricted upper opening 37 throughwhich a` loop of wire 33 projects. Bristles or strands of material 34 are looped in said wire loops and drawn tautinto the enlarged openings 32, as shown. Grease is pumped into cham bers by any suitable means such as the flexible tubes 35, connecting therewith from the reservoir 36, and the grease passes through the restricted openings 37 alongthe bristles,

keeping the brush or swabber constantly M,

lubricated on all five sides, so as to thoroughly grease the interior ot the pan as the same is moved therethrough. The top covers 38 of the brush being secured to the bar 29 is moved back and forth, right and lett, looking at Fig. 1, as the cam 8 rotates. The longitudinal movement, which takes place as These brushes are' each group of pans is greased, isestablished through the medium of the roller 12 which oscillates the shaftV 14 and crank 38 connected by balljoint to the rod 39, and in turn to the upright 19 by the block 40. This longitudinal movement travels with and against the `feed oi the pans 41, which for the purpose of illustration are illustrated inr groups of four, and as the :tourpans have been greased, the` brushes sweep backwardly to grease the next group of four, feeding forwardly with the same.

During the greasing operation, the brushes descend with the rods 25, 26 secured thereto, the same being raised and lowered by the bracket 12, secured tothe rod 28, and connected by the pin 43 and ball joint44 to the rod 45, connected by ball joint 46 to the lever pans 41 are moving through the conveyor, a

group of brushes automatically lubricated, pass down the left ends into the pans, moving along the same, greasing the ends, both sides, the bottom, and finally lifting out, greasing the opposite ends of the pans betore moving in an opposite direction to the feed of the pans to start the greasing oi' the next group, and so on. This greasing operation continues with each group of pans of predetermined number, according to the number of brushes employed. 48, L19 indicate the slideways or fixed base of the conveyor, the spaces 5() between the same being adapted for engaging and moving the pans, and 51,

52 indicate theV side angles or guides between o which pans are guided in their passage along the conveyor. Any well known form of pumping mechanism may be employed in the grease box 36, and of course various modifications may be made in the construction and arrangement of parts without departing from the spirit ot' the invention as claimed.

lVhile I have described the combination of a transverse rectilinear movement With a longitudinal movement, I have found in some cases that it is preferable to provide a double rectilinear' movement to each longitudinal movement, that is to say, as ;the brushes move longitudinally with the feed of the pans, I have found itfprefferable in some instances to grease the pans twice, first moving in the direction of the operator, then in thel reverse direction, thus insuring a thorough greasing 'ofthepa'ns before t-he brushes return counterwfeedwise for a new application-of the grease, but of .course the number of `greasing's may `be varied according tothe purpose inteinled. Infact, the device is susceptible of application for coating the interiors of containers with materials otherthan .grease or oil, and likewise may be used for cleaning pans byemploying .sti iler bristles, such as lot line wire, and for various other purposes.

I claim l. In a device ofthe class described, means for feeding .containers in position to be greased, means` for inserting .non-rotatable greasing elements therein andfor moving the .same across the entire interior surface of said. containersanduneans for withdrawing said greasers and removing said containers.

2. In a device Iof the class described,n1eans for. feeding containers in position to be greased, means for inserting non-rotatable greasing elementstherein and for moving thesame in contact with all interior sides of each of said containers,` and means for withdrawing said elements and removing said containers. I

3. In a device of the class described, an applying l element, means .for moving the same downwardly .and forwardly in one direction and then downwardly and rearwardly in the reverse direction in contact with the interior surfaces of a container.

l .11.4 In `a :device ofgthe class described, a conveyor feeding a plurality of pans, greasing mechanism including a plurality of nonrotating greasing members each adapted to be introduced into and moved laterally in each of said pans, and means for greasing the interiors ofgroups of said pansv suc,- cessively by said members while theV same are fed. i

5. In device of the class described, a conveyor feeding a plurality ot pans. greasing mechanism including a plurality of greasing members each adapted to be .introduced into and moved about each of said pans, and means for greasing the interiors of Vgroups of said pans successively by said members while the same are fed, said mechanism having a rectilinear movement transverse of the line of feed, `and a movement parallel thereto.

G. In a deviceof the class described, nonrotating means for applying material to the insides of acontainer and means for mov ing said irst mentioned means downwardly into and forwardly and upwardly out of said container.

7. In a device of the class described, a conveyor and pans thereolna greasing device, and means for raising vand loweringI the same and for laterally and transversely moving the same in one of said pans, and in combination therewith means for moving succes sive pans in position for the introduction and movement of said greasing device.

In testimony whereof I hereunto aliixv my signature. FREDERICK FRANZ.
